Laser depilation This is a method of permanent hair reduction that uses a laser beam. The light energy penetrates the epidermis and is absorbed by the melanin in the hair follicle, leading to thermal damage to the follicle and a gradual inhibition of hair growth. The treatment does not remove the hair mechanically, but affects its ability to regrow in subsequent growth cycles.
Laser depilation It is performed as an aesthetic medicine procedure on various parts of the body, for both women and men. It most commonly involves the legs, underarms, face, back and bikini line.
Laser hair removal – how it works
The basis for action laser depilation This is the phenomenon of selective photothermolysis. The energy from the laser light is absorbed by melanin, which allows for precise targeting of the hair follicle whilst minimising the impact on the surrounding tissues.
As a result of energy absorption, the energy is converted into heat, which damages the structures responsible for hair growth, including the matrix cells and the hair papilla. This damage affects active hair follicles and is permanent.
The effectiveness of the treatment depends on the hair’s growth phase. The best results are achieved during the anagen phase – that is, the active growth phase – when the hair remains firmly attached to the dermal papilla. As hairs are at different stages of the cycle at any one time, a series of treatments is necessary.
Laser hair removal – applications
Laser depilation It is used to achieve long-term hair reduction and to minimise skin problems caused by traditional hair removal methods.
The most common indications are ingrown hairs, folliculitis and recurrent skin irritation following shaving or mechanical hair removal.
The method is also used in cases of excessive hair growth caused by hormonal or genetic factors, where other forms of treatment prove insufficient.
Laser hair removal - contraindications
Contraindications to laser depilation These include, amongst others, pregnancy, the breastfeeding period, a recent tan, the use of photosensitising medicines and substances, active skin infections, certain dermatological conditions, and a tendency to develop keloids. Treatment with isotretinoin may also be a contraindication.
Other contraindications include blood clotting disorders, anticoagulant therapy, epilepsy, cancer and active autoimmune diseases. In certain cases, the presence of electronic devices, such as a pacemaker, may also be a factor, depending on the treatment area.
